In addition, some tumours can now be identified by molecular genetic analysis, for example, NUT (NUclear protein in testis) carcinoma and SWI/SNF chromatin remodelling complex, particularly its subunits SMARCA4 (BRG1)- and SMARCB1 (INI-1)-deficient carcinomas [41,42]. The gene discussed is SMARCA4; the disease is carcinoma.
